Benefits of technology

[0018]As an alternative approach, possibly giving a higher degree of security at the cost of more false alarms, other embodiments can use identifiers of decoders a

Problems solved by technology

One type of undesirable computer data which it may be wished to exclude from a computer system is copyright infringing or otherwise unauthorised video data.
There has also arisen a problem with unauthorised and/or copyright infringing video data being distributed via the Internet and other mechanisms.
These compressed versions are often pirate, copyright-in

Embodiment Construction

[0037]FIG. 1 illustrates a computer network 2, such as a corporate computer network, comprising a gateway server 4, a file server 6 and a plurality of client computers 8, 10, 12. The network 2 is connected via the Internet to provide a plurality of sources of data. Some of these sources of data may be sources of legitimate data, such as an FTP server 14 containing a legal copy of a video file that can be downloaded and used by appropriately authorised persons connected by the Internet. Conversely, another FTP server 16 may store a copy which is a pirate, copyright-infringing version of the video concerned and which it is desired to prevent from being manipulated within the network 2. An email server 18 may serve as a source for the banned material, such as email messages containing the banned material as an email attachment. There are also known number of file sharing schemes whereby banned computer files, such as pirate, copyright-infringing versions of computer files are stored on...

Abstract

Computer data containing compressed video data is examined to see if it is banned computer data, for example containing pirate or copyright-infringing video material, by examining the identifier of the video codec associated with the compressed video data. Certain video codec identifiers are highly correlated with the computer data concerned being banned computer data. Thus, an examination of the header file of the computer data may be used as an efficient and sensitive tool for identifying the computer data as banned computer data.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to the field of data processing systems. In particular, this relates to the detection of computer data containing compressed video data as banned computer data, such as, for example, computer files or streamed computer data containing a copyright infringing movie.[0003]2. Description of the Prior Art[0004]It is known to provide malware scanners, which may for example be web access scanners, email scanners, on demand file scanners, on access file scanners and the like, that serve to detect malware within data being stored, received, manipulated or used in some other way. The threat posed by computer viruses is well known. It is also important in other circumstances, particularly to many businesses, that their computer systems should not be used in connection with improper, inappropriate or otherwise undesirable computer data. As an example, email scanners may be used to scan email traffic for the p...
